Re: "Hymn template" snippet

[Dan Eble]

Gilles,

I would like to learn the reason for using \breathe and \bar "||" in the 
LilyPond snippet entitled "Hymn template" [1],   Are they intended to 
communicate two different things, or was it merely a stylistic decision to use 
\bar "||" at the end of a system and \breathe in the middle?

Also, why not use \bar "|." at the end?

I want to revise this snippet to use \caesura (which is still under 
development) to end phrases, but I want to stay faithful to your intent.

Thanks,
Dan
